RAILROAD-RAIL.

Specification of Letters Patent.

Patented Jan. 22, 1907.

Application filed May 8, 1905. Serial No. 259,454.

To all whom, it muy concern:

Be it known that I, MARK W. TRIMBLE, a citizen of the United States,residing at Idabel, in District 24, Indian Territory, have inventedcertain new and useful Improvements in Railway-Rails, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

My invention relates to new and useful improvements in railway-rails,and more particularly to that class wherein devices are employed toprevent the cars from leaving the track, one of the objects being toprovide a device of the character described that shall be simple inconstruction, durable, and effective in operation.

A further object of my said invention is to provide a device of thecharacter described whereby means shall be formed integral with therail, which effectually prevent the cars from leaving the `track when byreason of broken flangesl or other accidents to the wheels they are sodisabled as to permit of their leaving the rail now commonly in use.

Other objects and advantages of my invention, as well as the structuralfeatures by means of which these objects are attained, will be madeclear by an examination of the specification, taken in connection withthe accompanying drawings, in which the same reference-numerals indicatecorresponding .portions throughout, and in which-- Figure 1 is a topplan of a railway-track constructed in accordance with my invention.Fig. 2 is a transverse section on line 2 2 of Fig. 1, and Fig. 3 is aperspective view of a portion of a rail constructed in accordance withmy invention.

1 designates a railway-rail constructed somewhat in the form of thewell-known T- rail now commonly in use.

2 designates the base of the rail, which eX- tends sufficiently beyondthe edge of the top 3 to permit of the spikes being driven through theholes 4 into the ties 5 instead of having j the heads of the spikesclench the outer edge of the base, as in the present well-known method.

6 designates a flange formed integral with the rail when cast and whichmay be disposed at any desired angle with the rail and extend to anydesired height above the same.

7 designates braces disposed at suitable distances apart and which passthrough the rails and are secured thereto in any suitable manner andvwhich have the effect of preventing the rails from spreading.

In operation when a swiftly-moving train is passing upon a trackconstructed in accordance with my invention and for any reason any ofthe wheels on either side should leave the track, so as to throw theflanges on top of the rail 3, the outer edge of the wheel will come incontact with the flange or proj ection 6, which would effectuallyprevent the cars from leaving the track, the wheels being suciently wideto allow those on the opposite side to still remain in engagement withthe top 3 of the opposite rail, and thus by the use of my invention manyof the accidents now caused by broken flanges enabling the cars to leavethe track would be avoided and trains would be enabled to run at a muchgreater rate of speed than `at present and with less danger than at theordinary rates of speed now attained.

Having thus described my saidinvention, what I claim as new, and desireto secure by Letters Patent of the United States, is-

A railway-rail having a base, a head, a web uniting the base and head,and a straight, upwardly and outwardly projecting guardflange extendinglongitudinally from end to end of the rail, said guard-flange beingformed integral with the web of the rail and projecting angularly fromone side of the web at a point below the head of the rail, substantiallyas shown and described.

In testimony whereof I hereunto afliX my signature in presence of twowitnesses.

MARK W. TRIMBLE.
